(Cl. 2237) This invention relates to trousers with an elastic waistband, which do not require any other supporting means.

The invention is characterised, as a new industrial product, by trousers the waist-band of which consists of a band of elastic fabric offering great resistance to elongation, united laterally to'a band of resilient fabric offering less resistance to elongation by a thin band of extensible but inelastic fabric to which the top of the trousers is sewn, this sewing being preferably effected with a slight tension upon the said extensible fabric, and the top of the trousers comprising a number of folds or creases or pleats, in such a way that the top of the trousers, with the resilient band less resistant to elongation, encircles the pelvis, while the waist-band formed by the band that offers greater resistance to elongation encircles the waist of the wearer.

As a modification, it is also characterised, as a new industrial product, by trousers the waist-band of which consists of a band of elastic fabric offering great resistance to elongation, the lower edge of which is sewn to the top of the trousers, preferably with a slight tension of the elastic fabric, another band of resilient fabric offering less resistance to elongation than the first band, having its upper edge sewn parallel to the latter and a few millimeters lower down, so as to bear upon the pelvis, while the first band grips the waist of the wearer.

The waist-band according to the invention is characterised in that it has more elasticity at its lower portion than in its upper portion, whereby, on the one hand, said last portion sustains the abdominal muscles while said lower portion may be easily deformed in accordance with the widening of the hips.

The accompanying drawings show diagrammatically, by way of example but not of limitation, one constructional form of the invention.

Figure 1 represents the top of a pair of trousers made according to the invention, seen in profile; and

Figure 2 shows partially the inside of the top of the same trousers.

Figure 3 is a partial perspective view of trousers equipped with two distinct bands of elastic fabrics offering different resiliency.

Figure 4 is a partial perspective view of trousers equipped with a single waist-band formed integrally by two bands of elastic fabrics offering different resiliency.

Figure 5 illustrates the relationship between the trousers made according to the invention and the wearer.

As shown in Figs. 1 to 3, 1 is the top of the trousers, with the side pocket 2, and the hip pocket 3. This trouser top comprises a number of pleats 4, 5 and 6. The edge 11 of the top of the trousers is sewn by stitchings 12, preferably with a slight tension, to the lower edge of a strip of elastic fabric 7 offering great resistance to elongation and forming a band encircling the waist and having a relatively small elasticity. This resilient band 7 is closed in any of the usual Ways, for instance by a hook 8 and a buttoned flap 9.

A few millimeters below the lower end of the resilient 2,757,381 Patented Aug. 7, 1956 p ce band 7, the upper edge of a band of resilient fabric 10 offering less resistance to elongation than the band 7 and therefore having a relatively high elasticity. Said band it encircles the pelvis.

This upper band encircling the waist, and the lower band oflfering less resistance to elongation, may form only a single strip as illustrated in Fig. 4. The two bands 7a and 10a, differing-in resiliency, are separated by a narrow strip 14 of inelastic extensible fabric which is sewn by stitchings 15 on the inner side of the trousers 1 at the top 11 thereof.

The trousers made according to the present invention comprises a wide waist-band forming a veritable abdominal girth in its upper portion projecting upward from the trousers top and, which, owing to its variable resiliency, renders it possible to provide an almost constant coefficient of gripping upon the hips, its lower portion freely depending from the trousers top inside the trousers. Furthermore, this fabric band being sewn on to the fabric of the trousers with a slight tension, some slight latitude of expansion is obtained, which completely accommodates all the variations of volume of the part of the body concerned, which is liable to vary with the different positions and attitudes of the wearer.

We claim:

1. In trousers, a waist-band formed by an upper band of elastic fabric offering a great resistance to elongation and adapted to encircle the waist of the wearer, a lower band of elastic fabric offering a resistance to elongation less than that of the upper band and adapted to encircle the pelvis of the wearer, and a thin band of inelastic extensible fabric laterally connecting said upper band to said lower band, said band of inelastic extensible fabric being sewn on the inner side of the trousers at the top thereof, whereby the upper band projects upward from the trousers top while the lower band freely depends from said top inside the trousers.

2. In trousers, a waist-band formed by an upper band of elastic fabric offering a great resistance to elongation and adapted to encircle the waist of the wearer, a lower band of elastic fabric offering a resistance to elongation less than that of the upper band and adapted to encircle the pelvis of the wearer, and a thin band of inelastic extensible fabric laterally connecting said upper band to said lower band, said band of inelastic extensible fabric being sewn on the inner side of the trousers at the top thereof, this sewing being executed with a slight tension upon said inelastic extensible fabric and the top of the trousers being formed with a plurality of folds, whereby the upper band projects upward from the trousers top while the lower band freely depends from said top inside the trousers.

3. In trousers, for forming a waist-band, an upper band of elastic fabric offering a great resistance to elongation adapted to encircle the waist of the wearer and sewn on the inner side of the trousers at the top thereof by its lower edge, and a lower band of elastic fabric offering a resistance to elongation less than that of said upper band, adapted to encircle the pelvis of the wearer and sewn on the inner side of the trousers by its upper edge parallel to the upper band and a few millimeters below it, whereby the upper band projects upward from the trousers top while the lower band freely depends from said top inside the trousers.

4. In trousers, for forming a waist-band, an upper band of elastic fabric offering a great resistance to elongation adapted to encircle the waist of the wearer and sewn on the inner side of the trousers at the top thereof by its lower edge, with a slight tension, and a lower band of elastic fabric offering a resistance to elongation less than that of said upper band, adapted to encircle the pelvis of the wearer and sewn on the inner side of the trousers by its upper edge parallel to the upper band and a few millimeters below it, whereby the upper band projects upward from the trousers top while the lower band freely depends from said top inside the trousers.

5. In trousers, an elastic waist-band formed by two parallel bands of elastic fabric the lower one of which has a resistance to elongation less than that of the upper one, said waist-band being secured at its zone separating said two bands only to the inner side of the trousers at the top thereof whereby the lower band is recovered by the trousers and freely depends from said top inside the trousers while the upper band projects upward from the trousers top.
